Television’s celebration of popular musicals in live broadcasts continues with “Grease: Live” on Fox, airing Sunday, locally less than live: tape-delayed to run 6-9 p.m. on KDVR-Channel 31.

“Grease” is the word but “Coke” will be a close second. The overall sponsor has landed a Coke vending machine onstage, front and center, among other mentions.

Unlike NBC’s recent efforts (“The Wiz” and, less spectacularly, “The Sound of Music”), “Grease” will be performed in front of a studio audience. How that affects timing and energy level remains to be seen.

Joanne Ostrow has been watching TV since before "reality" required quotation marks. "Hill Street Blues" was life-changing. If Dickens, Twain or Agatha Christie were alive today, they'd be writing for television. And proud of it.
